Abstract: A software which is used to simplify logic function is introduced in this paper.The simplifying principle is based on a new method of logic function simplification.The data base technique is adopted while compiling program because the truth tables and implication tables used in the simplification method are all two-dimension forms.This paper comprises the overall design conception of the software and three special module's design idea.Different from the usual management and control software,this software is unique in its design method and proved to be exact.
